Welcome to Radiation Oncology Associates

Radiation Oncology Associates is a group of ten board certified physicians who provide radiation oncology care and expertise in Fairfax, Loudoun and Prince William Counties, as well as the city of Alexandria. Effective, safe and compassionate care of the whole person and their family is our top priority, made possible by our multidisciplinary approach and personalized philosophy that is unparalleled in Northern Virginia. We provide cutting-edge, precise radiation therapy for a comprehensive range of malignancies including central nervous system, head and neck, thoracic, breast, upper & lower gastrointestinal, genitourinary, gynecologic, musculoskeletal, skin, lymphoid & myeloid, blood, as well as pediatric cancers. We are highly experienced in treating benign conditions such as heterotopic ossification, Dupuytren’s contracture, desmoid tumors, keloid scars, and gynecomastia.

The best cancer care requires dedicated and compassionate providers who understand the complexity of your needs. Each of our new patient’s cases undergoes individualized, thoughtful review and discussion at our weekly radiation oncology physician conference. With the goal of maximum efficacy and optimal safety in mind, new radiation plans for our patients must also pass our weekly radiation oncology peer-review process. This important review meeting brings together the input from our ten board-certified radiation oncology physicians, as well as nurses, radiation therapists, medical physicists, medical dosimetrists, and social work specialists. Advanced and complex cancer cases are further discussed in person with experienced surgeons and medical oncologists at our specialty-specific multidisciplinary tumor boards. While receiving radiation therapy, our patients benefit from weekly physician and nursing checkup visits, and daily physician verification of the accuracy, precision and safety of your treatments. Our commitment is to healing the whole person and to achieve the best outcomes for your cancer treatment.
